I live in northern IL and own a 15 year old home that is moderately well insulated and is a little over 4000 sq ft. I have done quite a bit of research and am having a difficult time choosing which wood boiler to go with. I want to use my boiler to heat my home and water heater, but will just use LP gas during the warmer months. I am not mechanically inclined when it comes to these types of devices, but can do all the manual labor involved in cutting and splitting my wood. So, any advice on a system that will be reliable and not break down would be greatly appreciated- want to get the best for my money becuase once I spend this kind of moneyms my wife is really going to hate me for making this investment and having it not work out. Thanks.
